Republicans are not adequately speaking out against the GOP front-runner's "outrageous proposal," top Dem says

No Republicans have said they would not back Donald Trump as their nominee

Washington (CNN)The chair of the Democratic National Committee said Wednesday that Republicans are not doing enough to repudiate Donald Trump's comments on Muslims, calling their criticism of the 2016 front-runner "mealy-mouthed."

"It cries out for a unified condemnation, which has not come in any shape or form from the Republican side," the Florida Democrat said. "Mealy-mouthed criticism that has come from some of the presidential candidates and unfortunately the Republican Party chairman, (Reince) Priebus, is outrageous. What they need to do is unequivocally state, each one of their candidates for president, that they would not support this man if he were their nominee."

Many Republicans quickly criticized Trump over his comments.

House Speaker Paul Ryan called the proposals unconstitutional and Senate Majority Leader Mitch McConnell said such a policy would be "completely inconsistent with American values."

"We need to aggressively take on radical Islamic terrorism but not at the expense of our American values," Priebus said Tuesday.
